Geng said the US aircraft flew south and north along the eastern border of the East China Sea Air Defense Identification Zone from 11:00 a.m. to 1:22 pm Tuesday, about 200 km to the east of the Diaoyu Islands.

The Chinese army monitored the entire process, carried out identification in a timely manner, and ascertained the type of aircraft.

“We need to stress that China will identify every aircraft flying in the air defense identification zone according to the country’s announcement of aircraft identification rules for the air defense identification zone,” Geng said.

“China is capable of exercising effective control over this airspace,” Geng added.

China announced the East China Sea Air Defense Identification Zone on Saturday. The US State Department and certain officials expressed concern after the announcement.

Pentagon spokesman Colonel Steven Warren said Tuesday that the US conducted a training exercise that had been planned for a long time. It involved two aircraft flying from Guam and returning to Guam.- Xinhua

US B-52 bombers challenge China’s new ADIZ

China’s latest move in defending its sovereignty is facing opposition from other countries. Two US B-52 bombers have flown over the Diaoyu Islands in the East China Sea, in defiance of the air defense identification zone set on Saturday. China is taking a measured response, while stressing that it has the ability to manage and control its airspace.

Just days after China announced the establishment of an air defense identification zone, or A-D-I-Z. The US sent two B-52 bombers through the zone and over the Diaoyu Islands

China’s defense ministry asserted it has the ability to control the airspace. It says it identified the aircraft and monitored the entire two hours and 22 minutes.

The US said it was a long planned training mission, and put its own spin on the matter to fault China.

“This unilateral action appears to be an attempt to unilaterally change the status quo in the East China Sea. This will raise regional tensions and increase the risk of miscalculation, confrontation, and accidents. We have made this case to China.” US State Department spokeswoman Jen Psaki said.

Japan, which claims the Diaoyu Islands as its territory, was quick to join its ally.

“Our stance is that China’s move cannot be accepted, and so I think the US is also dealing with the issue with the same stance.” Japanese defense minister Itsunori Onodera said.

Aircraft flying through an A-D-I-Z must report a flight plan, maintain two-way radio contact and respond to identification inquiries, or face defensive emergency measures.

More than 20 countries and regions use such zones, including the US and many of China’s neighbors.

The Foreign Ministry called for calm, saying the zone does not target any country.

“China’s establishment of an air defense identification zone over the East China Sea is a legitimate exercise of the right of self-defense. It’s not aimed at any particular country or target. So we hope that the countries concerned will not overreact or panic over the event.” Chinese Foreign Ministry spokesman Qin Gang said.

China has also lodged protests over US and Japanese criticism. The country says the establishment of the zone has a sound legal basis and is in accordance with common international practice.
